Strategies

A diversified book, anchored in arbitrage

We do not forecast market direction; we measure relationships between prices. Every strategy follows the same principle: identify an explainable pricing dislocation, then capture its convergence within a strict risk budget.

The life cycle of an arbitrage trade

A position opens when the spread leaves its mean level beyond a statistical threshold, and unwinds as the price relationship converges. Every step is tested against risk limits and liquidity constraints.

    Monitor

    Thousands of price relationships tracked and standardised in real time.

  2. 02

    Trigger

    A signal fires when the dislocation clears its threshold and liquidity allows.

  3. 03

    Enter

    Algorithmic slicing controls impact cost and slippage on the way in.

  4. 04

    Converge

    As the relationship reverts, the position unwinds and releases risk budget.

Book

Six strategy families

Each family has its own signal source, capacity limit and risk allowance. Because they correlate weakly, together they make the portfolio robust.

01

Statistical arbitrage

Cointegration · mean reversion

Pair and basket portfolios built on cointegration and mean-reversion properties, capturing short-horizon dislocations at medium to high frequency.

  • Cointegration testing and pair selection
  • Residual signals and half-life modelling
  • Sector and style neutrality
02

Cross-market arbitrage

Venues · linked products

Monitoring spread structures across venues, contracts and closely related products to capture the reversion of structural dislocations.

  • Cross-venue spread monitoring
  • Relative-value models for linked products
  • Impact cost and capacity constraints
03

Basis and cash-and-carry

Physical · carry · delivery

Physical trade resources combined with derivative positions to build low directional exposure around basis, carry and delivery logic.

  • Warehouse receipt and logistics cost modelling
  • Cost-of-carry curve fitting
  • Delivery month risk management
04

Volatility arbitrage

Implied vs realised

Delta-neutral portfolios centred on the gap between implied and realised volatility, capturing mispricing in the volatility surface.

  • Volatility surface fitting
  • Dynamic Greeks hedging
  • Skew and term-structure opportunities
05

Calendar and event spreads

Term structure · events

Time-dimension spread portfolios around contract expiry, index rebalancing, seasonality and industrial cycles.

  • Roll path optimisation
  • Statistical testing of event windows
  • Seasonality factor library
06

FX and rates hedging

Forwards · swaps

Serving cross-border settlement and capital flows, managing currency and interest rate exposure through forwards and swaps.

  • Forward and swap structures
  • Settlement cycle matching
  • Tiered exposure management
